I'm cold steeping 400g of black malt currently - hopefully this will give some roasty notes but not be overpowering. (I took a punt on 400g cold steeped giving about the same colour contribution as the 231g in the mash)
Recipe as provided by Seymour:
I will be pitching with 2nd gen SO4 and plan to dry hop with about 50g of Cascade later on.seymour wrote: PISCAMOUR AMERICAN BROWN
Being a Piscator and Seymour collaboration brew. All aboard the "Cascadian Dark Ale" bandwagon.
6 US gal = 5 Imperial gal = 22.7 Liters

80% = 9.07 lbs = 4.11 kg, Pale Malt
12% = 1.36 lbs = 617 g, Torrified Wheat
2% = .23 lb = 104 g, Crystal Malt
1.5% = .17 lb = 77 g, Chocolate Malt
4.5% = .51 lb = 231 g, Black Malt
MASH low at 149°F/65°C for 60-90 minutes for maximum fermentability.
RAISE temp to 172°F/77.8°C, then VORLAUF, then SPARGE to collect 7.5 US gal/6.2 Imp gal/28.4 L pre-boil.
BOIL 60 minutes

33.3% = 1 oz = 28 g, Cascade, first wort addition
33.3% = 1 oz = 28 g, Cascade, 20 minutes remaining
33.3% = 1 oz = 28 g, Cascade, 5 minutes remaining, steep until chilled
It's going to be a busy morning - I have to bottle the Jims ESB and harvest the yeast while the mash is on for this brew... oh well, no rest for the wicked

See you tomorrow.
Cheers
Steve
Edit:-
Hops weighed out and ready for the morning... oh man they smell AMAZING, chock full of blackcurrant! I have high hopes for this one.
Water tested - surprising drop in alkalinity from normal so AMS amount adjusted accordingly
TDS where expected so salts weighed out accordingly
